So you want to maximize your rental property's potential. A rental cash flow calculator shows you how much profit you're really making. It factors in rent expenses and other details so you know what to expect each month.

By using basic information about your property you'll see whether you're on track for strong returns. This simple tool gives you a clear view of how changes in rent mortgage or maintenance can affect your bottom line. It helps you plan confidently and invest wisely.

What is Rental Cash Flow?

Rental cash flow is the net profit a property generates after subtracting all expenses (mortgage, taxes, maintenance, vacancies) from rental income. It’s the actual cash left in your pocket each month or year. Positive cash flow means the property earns more than it costs, while negative cash flow indicates losses. Investors use this metric to assess profitability, not just appreciation. Unlike accounting profits, cash flow reflects real liquidity, showing whether a rental property is self-sustaining or requires additional funding.
